Hi George,
Would you agree to pointing with the hand though when cutting with a bokken?

I try to project forward with the result that my hand forms a very similar shape to my forearm as you would find practicing oi tsuki (first knuckles of the index and middle finger pointing more forward of the other knuckles).

Its not flicking in the same way I described but it does extend more than trying to keep my wrists dead-straight... I have far more background in Karate (Kyokushin) than Aikido so I do find there is a lot of carryover...
